China is one of the countries with the largest desertification area, the largest affected population and the most serious sand hazards in the world. Over the years, China has continued to promote desertification control, and has realized the historic transformation from "sand entering and people retreating" to "green entering and sand retreating". Among them, Mengcao ecology has been practiced for nearly 30 years, collecting, domesticating, cultivating drought-tolerant, sand-tolerant, stress-resistant desert plants, under the navigation of digital technology, innovative research and development of machinery, equipment, technology, materials, new processes, integrated desertification control technology system, demonstration and engineering promotion, has accumulated more than 10,000 acres of light, medium and severe desertification land.
Native provenance guarantees ecological restoration
Provenance is the core of desertification prevention and control. It has been rooted in the Alxa Desert and Bayannur saline-alkali land and other important ecological regions in the north for many years, and has built a research institute of psammophyte and halophyte seed industry in desert areas, collected and domesticated desert plant germplasm resources with drought tolerance, wind and sand tolerance, and strong stress resistance, introduced and domesticated more than 200 species of native plants, carried out space mutagenesis of 34 grass species, obtained 6 national plant variety rights, and 32 grass varieties have been approved by the state and the autonomous region.
Research Institute of Psammophyte and Halophyte Seed Industry in Desert Area.
Among them, the approved Barhu Sheep Grass, Bar Tiger Grass Astragalus membranaceus, Sanhe Yanmai grass, Xilin Gol North China camel velvet quinoa, Tengger Mongolian leek, transformed Mengnong No. 1 Mongolian Ice Grass, Grassland No. 3 Mixed Flower Alfalfa, and desert plant varieties such as Bawang, S. canopy, sea buckthorn, S. buckthorn, S. shallot, white thorn, S. sand rice, etc., provide provenance guarantee for different types of desertification control and restoration.
According to different regions and different site conditions, innovative research and development of seed ecological packages according to local conditions can make the restoration of degraded, desertified and salinized grasslands more efficient, accurate and convenient, and provide experience for the application of native grass species in desertification control.
Sandy land treatment seed ecological package: With a variety of xerophytic and strong xerophytic plants as the core, combined with nutrients and water-retaining agents, the seed ecological package for sand land treatment is developed according to local conditions, and applied to the four major sandy lands and eight desert edges in China. Among them, 6 varieties are certified varieties for the protection of Mongolian grassland origin, and 1 set of corresponding planting technical regulations.
The numbers speak for themselves, but they show the dramatic changes. From 0 to 1, from scratch, generations of sand control people have planted green vitality into the yellow sand with practical actions. Mengcao ecology will also continue to rely on the conservation and multiplication system of native germplasm resources to provide a full provenance guarantee for sandy land management.
